Measurement of the branching fractions and $CP$ asymmetries of $B^+ rightarrow π^+ π^0$ and $B^+ rightarrow K^+ π^0$ decays in 2019-2021 Belle II data

Posted by klaurent Tokyo

Kavli Affiliate: T. Higuchi | First 5 Authors: Belle II Collaboration, F. Abudinén, I. Adachi, K. Adamczyk, L. Aggarwal | Summary: We determine the branching fractions ${mathcal{B}}$ and $CP$ asymmetries ${mathcal{A}_{{it CP}}}$ of the decays $B^+ rightarrow pi^+ pi^0$ and $B^+ rightarrow K^+ pi^0$. The results are based on a data set containing 198 million […]

Switchable moiré potentials in ferroelectric WTe2/WSe2 superlattices

Posted by klaurent Cornell

Kavli Affiliate: Jie Shan | First 5 Authors: Kaifei Kang, Wenjin Zhao, Yihang Zeng, Kenji Watanabe, Takashi Taniguchi | Summary: Moir’e materials, with superlattice periodicity many times the atomic length scale, have enabled the studies of strong electronic correlations and band topology with unprecedented tunability. However, nonvolatile control of the moir’e potentials, which could allow […]

Gravitational waves from rapid structure formation on microscopic scales before matter-radiation equality

Posted by klaurent Tokyo

Kavli Affiliate: Misao Sasaki | First 5 Authors: Marcos M. Flores, Alexander Kusenko, Misao Sasaki, , | Summary: The existence of scalar fields can be probed by observations of stochastic gravitational waves. Scalar fields mediate attractive forces, usually stronger than gravity, on the length scales shorter than their Compton wavelengths, which can be non-negligible in […]
